An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-9500 in the wild and no public exploit code.\n\nAffected product: IPC-HX2XXX Series,IPC-HXXX5X4X Series,IPC-HX5842H,IPC-HX7842H,NVR 5x Series,NVR 4x Series,SD6AL Series,SD5A Series,SD1A Series,PTZ1A Series,SD50/52C Series. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-9500/ (Markdown: https://insights.sbomify.com/CVE-2020-9500/index.md)","id":"CVE-2020-9500","markdown":"https://insights.sbomify.com/CVE-2020-9500/index.md","name":"CVE-2020-9500","record":{"aliases":["GHSA-wc34-c3wp-3988"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Dahua security cameras","requires_auth":"high_privilege","summary":"Authenticated attackers can crash Dahua security devices by sending specific log query commands, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dahua","cpe":[{"product":"ipc-hx2xxx_firmware","vendor":"dahuasecurity"},{"product":"ipc-hx5842h_firmware","vendor":"dahuasecurity"},{"product":"ipc-hx7842h_firmware","vendor":"dahuasecurity"},{"product":"ipc-hxxx5x4x_firmware","vendor":"dahuasecurity"},{"product":"n42b1p_firmware","vendor":"dahuasecurity"},{"product":"n42b2p_firmware","vendor":"dahuasecurity"},{"product":"n42b3p_firmware","vendor":"dahuasecurity"},{"product":"n52a4p_firmware","vendor":"dahuasecurity"},{"product":"n52b2p_firmware","vendor":"dahuasecurity"},{"product":"n52b3p_firmware","vendor":"dahuasecurity"},{"product":"n52b5p_firmware","vendor":"dahuasecurity"},{"product":"n54a4p_firmware","vendor":"dahuasecurity"},{"product":"n54b2p_firmware","vendor":"dahuasecurity"},{"product":"ptz1a_firmware","vendor":"dahuasecurity"},{"product":"sd1a_firmware","vendor":"dahuasecurity"},{"product":"sd50_firmware","vendor":"dahuasecurity"},{"product":"sd52c_firmware","vendor":"dahuasecurity"},{"product":"sd5a_firmware","vendor":"dahuasecurity"},{"product":"sd6al_firmware","vendor":"dahuasecurity"}],"cvss":{"score":4.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"Some products of Dahua have Denial of Service vulnerabilities.
